I've noticed some white and green residue around the terminals of my batteries that I installed in my van. This stuff wasn't there when I first put them in. Considering that the outside temperature can reach up to 100°F during the summer, I'm wondering if this is a sign of a problem. Should I be worried about this corrosion, and does it affect the performance of the batteries? I'll post some photos once I get back to the site.

What you're seeing looks like typical corrosion for lead-acid batteries. No need to panic! It happens sometimes, especially with temperature changes. Just do a quick Google search for 'how to clean battery terminals,' and you'll find easy instructions to tackle this. You can also find tips on how to prevent it from happening again.
If the corrosion is mainly on the positive terminal, it could mean overcharging, and if it's on the negative, it might indicate undercharging. Keep an eye on your battery's performance—if you're noticing shorter usage times, check the connections and clean them up!
Yeah, that's just battery corrosion. You can clean it off using a wire brush and then apply a little grease or Vaseline to the terminals to help protect them. It's a pretty straightforward fix!
